t 1 claim. l. 114-61) quirements, and it is therefore an object of thisinvention to provide a simple, practical and economical boat or craftwhich is'ideal for such events and purposes, and which is uniquein thatby elevating the boat body above the water and suspending the same onfloats and outriggingthe floats, so to speak, the users may employ thecraft safely and minus the peril which attends the type of boat whichmight capsize when merrymaking games and amusement activities often makethe occupants careless and overly simulated.

In carrying out a preferred embodiment of the invention, a simple boatbody is employed. This resembles, generally speaking, a rowboat having aflat bottom, length wise side walls or gunwales, bow and stern ends anda simple arrangement of seats therein, much like any ordinary rowboat.Instead, however, of resting atop the water, the boat body is suspendedin an elevated position above outwardly positioned floats. The floats,in turn, are operatively connected with the bottom of the boat by way oftrusses.

An object of the invention is to provide trusses which are extensibleand contractible so that the positions best desired for the floats inrespect to the side walls of the boat may be established and maintainedto assure balance of the boat proper and to obviate the likelihood thatthe same might capsize if rocked and otherwise playiully handled by theoccupants.

In addition, novelty is predicated on the stated boat body which is suchthat the forward and rearward ends of the float extend beyond the bowand stern, and wherein said boat is rigged along the bottom portion ofits side walls with flanges, said flanges being adjustab'ly anddetachably bolted on the bight portions of the trusses so that it isalso possible to rely upon this extra adjustment feature to bring aboutand maintain the safety balanced factor of the over-all structure.

Other objects, features and advantages will become more readily apparentfrom the following description and the accompanying sheet ofillustrative drawings.

In the drawings, wherein like numerals are employed to designate likeparts throughout the views:

Figure 5 is a similar exaggerated. detail sectional view on the line 5-5of Figure, 1, looking in-the direction of the arrows; and

Figure 6 is a view like Figure 1, showing a slight modi fication in theconstruction. 7

By way of introduction to the detailed description, it is to be pointedout that the boat may be moved in the water by way of paddlesor oars(not shown), or an outboard motor or, an equivalent source of power maybe provided (not shown). Since the novelty is not such that it includesthe powering means, it has been thought on necessary to incorporatethesame in this disclosure.

Referring, now to the drawings with the aid of reference niunerals andaccompanying lead lines, the boat body or box, as it is sometimescalled, is referred to generally by the numeral "8. fIt is similar toany ordinary rowboat and includes a suitable flat bottom 10,longitudinal side walls or gunw ales 12, a tail board or stern 114, anda suitable front wall construction 16, which may be treated as a bow. Onthe interior are appropriate cross-boards 18 providing seats. for theoccupants. The numeral 20 designates a steering wheel operati-velyconnected with a rotatably mounted steering post 22 which is equipped asshown in Figure 1, with an appropriate pulley or drum 24 and pulleys orguides .26 which serve to accommodate a cooperating portion of steeringcord-s. 'Ihe lengthwise portions of the cords are denoted by thenumerals 28 and extend suitably toward the rear of the boat where theyare trained over additional pulleys 30 and connectible with bellcranksor the like 32 which operate the steering rudders 34 at the rear. *Inthe form of the invention shown in Figure l, there is a tie connection'36 between the rudders including tie rods 88 and a connectingturnbuckle 40. Ihe rudders are hingedly or pivotally mounted, .as at 42(see Figure 2), on the rear end of the aforementioned pontoons oroutrigged floats 144. These may be suitable buoyant aluminum tubes whichare substantially ovate in cross-section, as shown in Figure '3, andhave pointed leading ends 416. It will be noted that the forward andrearward ends of the floats extend well beyond the bow and stem of theboat body 8. flhe boat body is suspended in a desired elevated positionabove and between the inner longitudinal portions of the floats. lhefloats are spaced from one another in parallelism, and are coplanar.They are rigged to the bottom of the float by way of a plurality ofsubstantially elongated U-shaped trusses made of pipes or rod members.Each truss is best shown in Figure 3, and it will be seen that eachtruss comprises complemental left and right sections 48 and 50 which areeach approximately L-shaped in general outline. The free end portion ofthe horizontal arm 52 is laterally ofiset, as at '54, to accommodate thefree end portion of the linearly straight limb or arm 56 of the section'50. lT-he' respective vertical portions or limbs 58 of the respectivesections are appropriately headed at '60 and suitably welded orotherwise connected with the crest portions of the respective floats.'It will be noted that the horizontal limbs or arms 52 and 5 6 areprovided with vertical bolt holes 62. The overlapping end portions serveto accommodate a bolt :64 and nut 66, thus providing the afore mentionedlengthwise extensible and retractibtle construction of each truss. Theseextensible and retraetible big-ht portions of the trusses underlie thebottom of the boat in the manner illustrated, and the horizontal limbsextend well beyond the side walls and the side walls are providedadjacent the bottom with rigidly attached angle irons having verticalflanges 168 and horizontal flanges 70.

The horizontal flanges have nut-equipped bolts 72 which are adjustablybolted to the existing bolt holes in the respective arms or limbsSQ'and'56, all as clearly brought out in Figure 3, taken in conjunction, forexample, in Figure .1, The enlarged details of these featuresare,

however; illustrated in the fragmentary sectional'views identified asFigures 4 and 5, respectively, as is clear;

With the construction just revealed; it is clear that the floats may beadjusted toward and from each other, and, when the boat body is properlycentered in respect thereto, the distance between each side wall andfloat may be thus regulated so as .to render the boat, as an over-allstructure, virtually non-capsizing. *It may be desirable, too, in orderto bring about this 'wel'l balanced result, to adjust'the' [boatforwardly or rearwardly relative to the leading and 'trailing ends 46'and 47 of the floats. The angle'ir'ons' or flanges and bolts and boltholes in the parts allow this desirable end to be successfullyaccomplished. i

In some instances, instead of restricting the construction to a pair ofcoplanar floats, it may be desirable to ample, in the modification seenin Figure 6. This .extra float is denoted by the numeral 74 and it isrelatively short and is located between the rear terminal ends 47 andhas its rear end projecting beyond said ends 47. Its forward endterminates rearwardly of the stern of the boat. Suitable guides aremounted thereon, as at 76, to accommodate the operating cords 78 for thesingle rudder 80 which is mounted onthe trailing end of the float 74 andwhich is controlled by rocker arms or the like'82. This'extra float issecured in place by rearwardly converging braces 84 which are fastenedon the rear end portions of the main float and have their convergingends fixed to the central longitudinal ridge or crown portion of theentra float 74." Otherwise, this construction is the same as thatalready described, and, therefore, the same reference numerals designatecorresponding parts throughout all of the views.

include an additional or third float, as shown, for ex- Reference to thepreceding specification and considering the same in conjunction with theillustrative drawings will enable the reader, it is believed, to obtaina clear and comprehensive understanding of the construction and featuresand advantages of the invention. .For this reason, a more extensivespecification is thought to be unnecessary.

Changes in shape, size, materials and rearrangement of details, such ascome withinthe spirit ofutheinvcntion or scope of the adjoined claim,may be resorted to in actual practice, if desired.
